The Central Statistics Office has published a list of goods that have been added to or removed from the inflation calculation from the 1970s to today.
The inflation figures here are based on what's referred to as a basket of goods that are representative of what people are buying and consuming.
The changes are illustrative of the alterations in consumption patterns down through the decades.
In 1975, for example, 'Vodka White' made its way into the basket of goods as the hot beef flavoured drink, Bovril, was removed.
In 1982, deep fat fryers were added, but black and white televisions were thrown out.
Also in that decade, foodstuffs such as grapefruit and doughnuts were added while fish fingers and semolina were removed.
Reflecting changes in entertainment patterns, Hi-Fis were added in 1982 but were out again in 1996.
Fast forward to 2016 and out went the fillet of plaice but in went hake, sweet potatoes and avocadoes.
And one addition in 2016 that would have left statisticians in the 1970s scratching their heads - streaming services.
The list comes ahead of the publication tomorrow of a rebase of the Consumer Price Index at which the CSO will outline updates to the items included in the national basket of goods and services.
